SPECIFICATION forming part of Letters Patent No. 432,882, dated July 22,1890. Application led April 14, 1890.` Serial No. 347,869. (Nomodel.)

Beit known that I, GEORGE J o RGEN LAE-` SON, a citizen of the UnitedStates, residing at Oarpentersville, in the count-y ofrKane and State ofIllinois, have invented a new and useful Wagon-Skein, of which the fol`Vlowing is a specification.

This invention relates to vehicles, and more especially to the axles andaxle-skeins thereof, and the same is an improvement upon all devices ofthis character heretofore made and applied to vehicles of any character.

The object of the invention is to provide a simple roller-bearingbetween the axle-skein and the hub or box which shall possess very fewparts, and yet have all the qualifications` and capabilities of a morecomplicated device, and this object I attain by the present invention,ashereinafter more fully described, and illustrated in the drawings, inwhich- Figure l is a longitudinal section of the parts assembled. Fig. 2is a cross-section thereof. Fig. 3 is a plan view, with the boxl androllers removed. Fig. 4 is an enlarged perspective view of one of therollers. Fig. 5 is an enlarged section, showing the manner in which theends of the rollers are loosely fitted in the grooves.

Referring to the said drawings, the letter A represents the ordinaryaxle or skein, which is provided at its innerend with an annularshoulder B, having a groove G, and at its outer edge a half groove orrecess H. The said skein is also provided near its outer end with asmaller annular shoulder b, having a similar groove g` and a half grooveor recess h on its outer face at its edge. Between these two shouldersfit the rollers R, whose bodies are slightly tapered throughout theirlengths, and which are provided with bearings or reduced ends r, adaptedto loosely enter the grooves G and g, but not to touch the sides orbottom thereof when the rollers are in place. The outer shoulder b isprovided with a notch N at its top, through which the outer end r of therollers R may be lifted, whereby said rollers canV be removed frombetween the shoulders when desired.

X is the hub of the metallic box, which fits therein, this box having aflange F at its outer end, which fits inthe recess h, and a recess R inits inner end,lwhich fits the recess H on the inner shoulder B when theparts are in position` By this means dust and dirt are prevent-ed fromentering the bearing, and the same is keptclean at all times. Y

T is the ordinary binding-nut screwed upon the threaded outer end O ofthe axle A, as will be understood. The relative sizes of these parts issuch that when they are in place the rollers will bear at their innersides upon the tapered exterior of the axleAand at their outer sideswithin the box X, and their journals r will thereby be held out ofcontact with either side of Vthe grooves within which they are seated.The shoulders at the ends of the rollers around their journals abutagainst the shoulders B and Z9, and the ends of the journals are therebykeptout of contact with the bottom of the grooves, and by thisarrangement all wear upon the journals when in their normal positionsisavoided. The diameters of the two shoulders B and b are such that theystand close to yet out of contact with the interior Vof the box X; butthe inner end of the latter abuts against the shoulder B and the innerside of its iiange F at its outer endl against the outer side of theshoulder l) to form a dust-guard, and the, nut T bears tightly againstthe outer shoulder l? and loosely against the iiange F. By thisarrangement the friction between the parts is further considerablylessened without detracting from their perfection of mechanicaloperation or increasing their friction. y

I claim as the salient points of this inventionl. The axle-skein A, theshoulders B and b at the inner and outer ends thereof, respectively,said shoulders having inwardly-facing grooves G and g, and the rollersR, having reduced ends r less in width and length than the width and thedepth of said grooves in which they are seated, whereby they will be outof contact therewith, in combination with the box B, fitting the outerface of the series of rollers, all substantially as and for the purposedescribed.

2. The axle-skein A, the shoulders B and b at the inner and outer endsthereof, respectively, said shoulders having inwardly-facing grooves Grand g, andthe rollers R, having re- IOO duced ends r less in width thanthe width of said grooves in which they are seated, whereby they will beout of contact therewith, in coinbination with the box B, fitting theouter face of the series of rollers, all substantially as and for thepurpose described.

3. The axle-skein A, the shoulders B and b at the inner and outer endsthereof, respectively, said shoulders having inwardly-facing grooves Gand g, and the rollers R, having reduced ends lr less -in length thanthe depth of said grooves in which they are seated, whereby they will beout of contact therewith, in combination with the box B, fitting theouter face of the series of rollers, all substantiall y as and for thepurpose described.

4. The axle-skein A, the shoulders B and b ,at the inner and outer endsthereof,rcspect-` ively, said shoulders having inwardly-facing grooves Gand g, the former having an inwardly-facing annular recess H and thelatter an outwardly-facing annular recess h, and the rollers R, havingreduced ends r, in coinbination with the box B, fitting the outer faceof the series of rollers, its inner end having an annular recess R,loosely fitting that in the inner shoulder and its outer end looselyfitting around said outer shoulder, an inwardly-projecting fiange F ontheI outer end thereof loosely fitting said recess h in the outershoulder, and a binding-nut T, screwed onto the outer reduced end of theaxle, all substantiall y as and for the purpose described.

5. The axle-skein A, the shoulders B and b .at the inner and outer endsthe-reof, respectively, said shoulders having inwardly-facing grooves Gand g, the former having an in-v wardly-facing annular recess H and thelatter an outwardly-facing annular recess h, and the rollers R, havingreduced ends o, in coinbination with the box B, fitting the outer fac'esof the series of rollers, its inner end loosely Afitting the recess H inthe inner shoulder and its outer end loosely fitting around said outershoulder, an inwardly-projecting ange F on the outer end thereof looselyfitting said recess` hin the outer shoulder, and a binding-nut T,

grooves G and g,the latterhaving an outwardlyfacing annular recess h,and the rollers R, having reduced ends r, in combination with the box B,fitting the outer face of the series of rollers, its inner end looselyfitting the inner shoulder, an inwardly-projecting flange F on the outerend thereof loosely fitting said recess h in the out-er shoulder, and abindingnut T, screwed vonto the axle, all substantially as and for thepurpose described.

7. The axle-skein A, the shoulders B and b at the inner and outer endsthereof, respectively, said shoulders having inwardly-facing grooves Gand g, the former having an inwardly-facing annular recess H, and therollers R, having reduced ends r, in combination with the box B, fittingthe outer face of the series of rollers, its inner end having an annularrecess R', loosely fitting that in the inner shoulder and its outer endloosely fitting around said outer shoulder, an inwardly-projectingflange F on the outer end thereof loosely fitting the outer' shoulder,and a binding-nut T, all substantially as and for the purpose described.

S. The axle-skein A, the shoulders B and b at the inn'er andouter endsthereof, respectively, said shoulders having inwardly-facing grooves Gand g, the latter having a notch N for the purpose Set forth, and therollers R, having reduced ends r, in combination with the box B, fittingthe outer face of the series of rollers, all substantially as and forthe purpose described.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in presence of two witnesses. A
